I bought this app for the sole purpose of throwing the balance to the left side of my hearing aids so that I can hear people from the right ear. I've gone to the settings and put the balance all the way to the left yet the sound still comes out both ears. Does it not control the sound throughout the entire phone? one for files playing through Poweramp? I have a radio streaming app that I'm using (Tune-in) I'm giving this 24 hours before I ask for a refund. Balance should be a basic function of an Android operating system so paying $4 for that feature didn't make me very happy...
